Feathercoin 0.8.7.0 Released - The NeoScrypt Update - Hardfork block 432,000

[nrg_wolf]

New cgminer 3.7.7b settings 4 U.

280x @stock 1020/1500 Hynix - 138-143 khash - catalyst 14.9 w/ 14.7-rc3 openCL files copied to cgminer's folder

-g 3, -w 64, -i 14  ..  HW and artifact free for 20 minutes now !

update

1 HW  

update ii

cgminer will randomly set the thread concurrency on almost every startup. eg. it chooses 4096 or 8192 or 16384.

I will soon know if the HW error was caused by the 4096 bin in use at the time. Currently running a 16384 bin..

36 hours later I'm averaging 139 khash with only 4 HW errors.

This is pretty much what I am getting as well, except my settings are slightly different. Also no matter how many times I try to regenerate a new bin file, my install will always pick 8192 for thread concurrency.

Code:

280x -i 13  -w 48  -g 2   GPU clocks 1025/1500 

http://img.techpowerup.org/141104/neoscript.jpg

I also have another box, basically identical build to the above (3x 280x cards) that prefers -g 1 instead of the -g 2 shown above, with all the other settings and clocks set the same.

What make/model cpu, mobo and ram are you running ?

My rig: Phenom II x6, Asus SB 990fx, GSkill 9-9-9-24 2T

I just bumped it up to 4 threads and gained 2 kash. WOOT !

It's a Gigabyte GA-Z77-DS3H with a Intel Celeron G1630 (2.8 GHz), ADATA 4 GB RAM, not sure timings, on Win 7 Pro 64 bit, 80 GB SDD (Intel).

Most of my rigs are a similar build as they were put together more with cost in mind for BTC, and eventually scrypt, mining last year. I pretty much stuck with Intel boards, so seeing you have AMD based rig might make the difference. When I mined scrypt the few AMD boards I did own seemed to not do as well, so I sold them off early this year when the prices started to drop off. Anyway, presently I have no way to compare between AMD/Intel based MB/CPU setups to see if that make a big difference.

Seeing the FTC profitability falling fast, I would like to get another 20 kHash or more per card out if possible, but seems to be hitting a brick wall with getting much past 140 kh right now.

I calculate my 3 X rig puts out a consistent 138 kh x 3 = 414 kh total. Power draw at the wall is around 540 watts, bringing me to roughly 0.76 kh/watt efficiency. I pay $0.11 per killawatt hour for power, so using today's calculations, I get the following:

Code:

Per 	Est. Rewards 	Pool fee 	Rev. BTC 	Rev. $ 	Costs 	Profit
Hour 	2.42729 	0.00000 	0.00020 	$0.09 	$0.06 	$0.03
Day 	58.25485 	0.00000 	0.00472 	$2.12 	$1.45 	$0.67
Week 	407.78395 	0.00000 	0.03303 	$14.86 	$10.16 	$4.70
Month 	1,747.64550 	0.00000 	0.14156 	$63.70 	$43.56 	$20.14
Year 	21,263.02025 	0.00000 	1.72230 	$775.04 	$529.98 	$245.06 

So while still slightly profitable, it would be nice to crank up the hashrate a bit more and stay in the black awhile longer.

you should be getting higher then that, my crappy elpidha cards to 144-150khs. try installing 14.7 rc 3 drivers instead of just using the files and fiddle the clocks alittle. i run my asus 280x's at 1135-1800, mainly because they can go that high. but that only really gains me about 12 khs. iam getting about 172 stable but downclocked i get about 160'ish.

Update:

Tried using the sgminer version posted earlier, same results as with cgminer.

http://img.techpowerup.org/141105/sgminer.jpg

Looks like I am stuck in the land of 140 Khash for now.

Tbh, I'm finding it quite peculiar that my 140 khash noob's config is the best we have for 3.7.7b. And how the only alternative is Wolf0's blacklisted site with it's nsfw .pngs and promises of higher hashrates (on a client that can't or won't solo mine), seeminly designed to lure people to said site.

wolf0s miner works well, iam useing his public release version. there is also an updated cgminer as well at 3.7.8 which has speeds similar to wolf0s.

I know you are all interested in mining (and holding), but let me highlight here that Lizhi made new version of wallet with multisig support.
He would really appreciate people testing this wallet.
So if you are interested, please continue here:

I am using Wolf modified neoscrypt140909.Cl file on my installs, so essentially it is the same as 3.7.8. I do have one rig running actually running the 3.7.9 and can confirm that my speeds are essentially the same. This is between rigs of both 7970 and 280x cards, which again are basically the same, but the road block for me seems to kick in at around 140 khash -145 khash. I have tried messing with clocks and settings, but to go from core clocks of ~1040 to 1150 for only a 1-2 khash improvement does not seem to be worth it considering my power draw from the wall goes up as well.

Just when I read people getting 160-175 khash out of similar setups using similar settings makes me think I am overlooking something simple, thus why I am asking for input.

Edit: I should add that all my GPU are using Hynix memory as those appear to be the cards capable of the 175 khash people are reporting.

What version AMD drivers are installed? 14.9?

What version AMD drivers are installed? 14.9?

Yeah 14.9. I just downgraded one rig to 14.7 RC3 on as suggested, and I do see an initial 5 kHash improvement. Right now running about 150-151 khash with 1040/1500 -w 48 -I 13 -g 1. Seems raising the core clock for me does nothing more and in some cases it even reduced the khash a bit. I am still fiddling with different settings, so holding out hope for a bit more....

I have four rigs, one with 14.6rc, 14.7rc, and the other 2 with 14.7rc3.  By far, the 14.6rc leads in hashrate with hd7970s over hd7970s in the 14.7rc and the 14.7rc3 with 280xs.
1000/1500 -w 48 -I 13 -g2.

I've been making SGMiner releases long before SG5 was a thought in anyone's mind. People trust me, especially because I sign shit with the same GPG key I use for bitcoin OTC. If you don't - fine. But until you have actual evidence of malware - hint: you will find none - quit with the bullshit.

If you cannot handle my simple questions and findings, then maybe you shouldn't be allowing others to examine or make use of your work.

You may know it is safe but the general public does not. Do you see how this "trust me or gtfo" mentality does nothing but stunt/slow Feathercoin's (and neoS mining) progress ?

Or maybe.. that is exactly what the crypto "elite" want. eg. limit/slow the competition's growth (thus why you borked solo mining neoS at the kernal level )

Feathercoin 0.8.7.0 released
The NeoScrypt Update

It has been a long time in the works but we have finally got NeoScrypt and a GPU miner so we can now release the Feathercoin 0.8.7.0 client with NeoScrypt set to replace Scrypt on block 432,000, this should happen on the 26th October 2014. There is a Twitter countdown to the hard fork available here.

NeoScrypt uses stronger components than the Scrypt we are familiar with. A key element of Scrypt is Salsa which adds memory complexity, the problem is that the version of Salsa in Scrypt is weak and has been broken by differential analysis which is why we see cheap and powerful ASICs. NeoScrypt uses a blend of Salsa and its successor Chacha set to a higher level of strength. In theory these two should not be broken for at least a decade, this gives better protection than simply adding hashing functions.

However the goal is not simply to avoid ASICs forever as this may not be possible though ideally we want to stay in reach of as many people as possible without the need for expensive mining equipment. As the majority of people buying Scrypt ASICs are not doing so to mine Feathercoin and the fact that some very large ASIC suppliers will be releasing products soon it seems sensible to move algorithm now before we face the challenges that hit many SHA-256 alts when the SHA-256 ASICs hit. We are moving to a new tier of hashing where Feathercoin can be the leading coin.

Please be aware that after the update your Scrypt mining setup will no longer work. You will need to use the new GPU miner that we have been developing for several months now. Not only do miners need to upgrade their software but pools do as well.

To me it looks like HippieTech is FUDing in the hope of deterring miners from using Wolf's version & thus increase his/her profitability.

Wolfs miner has been on my PIMP rig since release with no issues.

Ok, let's get back to the technical aspects of mining this coin.

I got my 7970 and 280x builds running stable anywhere from 150 khash to 160 khash, so from what I been reading I am pretty much topped out unless Wolf wants to release his private kernal.

Now I want to try to get some of my 270x boxes to work. Right now I can get them to around 60 khash on each card on Linux, which seems awfully low compared to the 280x builds. I have tried a Windows build and can get ~75 khash for awhile, but I cannot get them to run stable. I get a ton of ATI driver restart messages before it eventually just crashes the whole rig. I can get maybe a hour of run time, but at this point the build is too unreliable to trust.

The 270 rig I have been playing with is Windows 7 Pro 64 bit on a 80 GB SSD, Intel CPU, Asus ZB7-A MB, and 4 Gig G Skill RAM. I have so far tried AMD driver versions 14.9 release, 14.9.1 Beta, 14.9.2 Beta, 14.6 beta, 14.7 RC3. I did have some stability with the 13.12 drivers, however I was back in the 55-60 khash ballpark with those no matter which clock speeds or settings I tried.

Hoping someone out there has had better luck with the 270 series and would be willing to share a few tips. I will take suggestions for either Linux or Windows builds if I can get in the 80 khash+ range. I believe I read someone was getting 90+ khash out of their 270's somewhere, but I could find no details.

The driver crashes are sometimes caused by a lack of system or pagefile memory. Set the pagefile to a MIN and MAX of at least 12gb and lets see what happens.

If you really want to get fancy, create a partition for it or move it to another drive. Some apps/games will also benefit from this.
